Finite Element Analysis of Electric Field Distribution in C4F7N as an Alternative to SF6 For Electrical Insulation

This research work examines the effect of the electric field in C4F7N for different configurations of electrodes and applied voltages. The behavior of the insulation medium is better understood by its electric field analysis. Sphere-sphere and plate-plate electrode configurations are analyzed with varying gap distances. A thorough electric field strength distribution analysis was carried out in a simulation tool based on the finite element method. The electric field strength is firmly dependent on the air gap between the electrodes and applied voltages. The electrodes configuration also affects the electric field and hence the breakdown strength of insulation gas.
